mkazantsev retitled this revision from "[SCEV] Re-enable "Use nw flag and symbolic iteration count to sharpen ranges of AddRecs", attempt 2" to "[SCEV] Re-enable "Use nw flag and symbolic iteration count to sharpen ranges of AddRecs", attempt 3".
mkazantsev added a comment.
Now isKnownPredicateViaConstantRanges is used for TODO check too, and Step is limited to the constant. If it still is not helping, then I have no slightest clue what it can be and need a reproducer for the problem.
